Why don't crows get electrocuted when they sit on electrical wires?

Crows don’t get electrocuted when sitting on electrical wires because they are not completing a circuit. Electricity flows through a conductor when there is a difference in voltage, and since a crow's body is not in contact with the ground or another wire with a different voltage, there is no path for the electricity to travel through them. As a result, they can safely perch on a single wire without being harmed.
